Petunia plant named ‘PDBVI35-0’

ABSTRACT

A new and distinct  Petunia  cultivar named ‘PDBVI35-0’ is disclosed, characterized by unique, fully double Violet flowers with mounding to trailing plant habit. Plants of the new variety are highly floriferous with exceptionally good branching. The new variety is a  Petunia , suitable as an outdoor garden or container plant.

Latin name of the genus and species: Petunia hybrid.

Variety denomination: ‘PDBVI35-0’.

The new Petunia cultivar resulted as part of a planned breeding program by the inventor Jun Tsukahara, in Yame, Fukuoka, Japan. The objective of the breeding program was to develop new Petunia varieties with interesting colors and attractive plant forms.

The new variety resulted from the crossing of the seed parent, an unnamed, unpatented proprietary Petunia seedling with the pollen parent, an unnamed, unpatented proprietary Petunia seedling in September 2006. The new variety was discovered in May of 2007 by the inventor in a group of seedlings resulting from that crossing, in a commercial greenhouse in Yame, Fukuoka, Japan.

Asexual reproduction of the new cultivar ‘PDBVI35-0’ by vegetative cuttings was first performed at a commercial greenhouse in Yame, Fukuoka, Japan in September 2007. Subsequently many generations have been produced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PDBVI35-0’ has not observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length and light intensity, without however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characeristics of ‘PDBVI35-0.’ These characteristics in combination distinguish ‘PDBVI35-0’ as a new and distinct Petunia cultivar:

-   -   1. Unique Dark Violet flower color.     -   2. Mounding and trailing plant shape.     -   3. Highly floriferous plant habit.     -   4. Fully double flowers.     -   5. Exceptionally good branching.

COMPARISON TO THE PARENT VARIETIES

Plants of the new cultivar ‘PDBVI35-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary seed parent. However, the new variety has fully double flower whereas the seed parent does not have a fully double flower. Additionally, plants of new variety have a more trailing plant habit than the seed parent.

Plants of the new cultivar ‘PDBVI35-0’ are similar in most horticultural characteristics to plants of the unnamed proprietary pollen parent. However, plants of the pollen parent produce flowers with a lighter color, and of a smaller size.

COMPARISON TO COMMERCIAL VARIETIES

The new cultivar can be compared to the patented commercial variety ‘KERPRILCOMP’ U.S. Plant Pat. No. 19,327. ‘PDBVI35-0’ is similar to this commercial variety in most horticultural characteristics, including double flowering, however, plants of the new variety produce much darker flowers, than ‘KERPRILCOMP’. Additionally the new cultivar has a more mounding habit than ‘KERPRILCOMP’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PDBVI35-0’ grown in a greenhouse, in a 10 inch commercial basket. Age of the plant photographed is approximately 20 weeks from 5 rooted cuttings. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
